What is a Single Channel Variable Volume Micropipette?
Example Volume Ranges:
- 0.1–2 µl
- 2–20 µl
- 20–200 µl
- 100–1000 µl
These micropipettes are widely used for precise liquid handling in scientific experiments.
Working Principle of Micropipette
The working principle of a micropipette is based on the air displacement mechanism.
How it works:
- Pressing the plunger creates a vacuum.
- When released, liquid is drawn into the tip.
- Pressing again dispenses the liquid.
This ensures accurate and controlled liquid transfer.

Key Components of Micropipette
Understanding the parts helps in better usage:
- Plunger Button – Controls aspiration and dispensing
- Volume Adjustment Knob – Sets required volume
- Digital Display – Shows selected volume
- Tip Ejector – Removes used tip safely
- Shaft – Holds the disposable tip
- Micropipette Tip – Disposable plastic tip for liquid handling
